Background: Few studies documented incidence rates of different types of stroke among patients with polycystic kidney disease (PKD).
Methods: We conducted a retrospective cohort study based on the National Health Insurance (NHI) Database of Taiwan. The PKD cohort comprised patients aged≥20 years diagnosed with PKD using inpatient claims from 1998 to 2011, excluding prior stroke.
Asbestos has been recognized as a human carcinogen associated with malignant mesothelioma, cancers of lung, larynx, and ovary. However, a putative association between gastric cancer and asbestos exposure remains controversial. In this study, we aimed to explore gastric cancer risk of workers potentially exposed to asbestos in Taiwan.

Methods: We established a retrospective cohort of workers employed in asbestos industries during the period of 1950-1989 and the occurrence of MPM during the period of 1980-2009 was examined with the Taiwan Cancer Registry. Estimated rate ratios (eRRs) were computed for each factory where any case of MPM was diagnosed by assuming Poisson distribution with a minimal latency of 20 years.
Background/purpose: Globally, asbestos-related diseases (ARDs) keep rising over the coming decades. The epidemic of ARDs will be a burden on public health. We aimed to predict the malignant pleural mesothelioma (MPM) incidence in the next 30 years for Taiwan based on historical asbestos consumption.

We recently found that MS also acts as a peroxisome proliferator-activated receptor-gamma (PPARγ) agonist, thereby promoting insulin sensitivity in C2C12 cells. However, the attenuation of hyperglycemia by MS treatment in vivo remains uncertain.

Methods: Using the National Health Insurance (NHI) database of all end-stage renal disease patients on maintenance dialysis registered from July 1997 to December 2005, we matched eligible PD patients with eligible HD patients on age, sex, and diabetes status. The matched patients were followed until 31 December 2006.
Background: Liquid crystal display (LCD) manufacturing involves three fabrication processes: array, panel and module processes, which result in different levels of volatile organic compound (VOC) exposure. The aim of this study was to assess the potential reproductive endocrine effects of occupational exposures during LCD manufacturing predictive of menstrual cycles as subclinical markers of female reproductive dysfunction effects of low-dose exposures.
Methods: A total of 94 fabrication workers were followed for one complete menstrual cycle using daily urine samples: 23 were from the array, 53 from the panel, and 18 from the module work areas.
Objective: Because of the increasing incidence and prevalence of diabetes as a leading cause of end-stage renal disease (ESRD) in the aging population, we estimated the expected life-years (LYs) saved from successful prevention of ESRD in elderly patients with diabetes.
Research Design And Methods: We conducted a population-based cohort study using the National Health Insurance Research Database. We identified all incidences of ESRD in the individuals >65 years of age who were receiving maintenance hemodialysis (N = 24,243) from the registry files of catastrophic illnesses in Taiwan from 1 July 1997 to 31 December 2005.
Objectives: To quantify the life years gained and financial savings by preventing a case of occupational cancer.
Methods: The authors retrieved data from the Taiwan Cancer Registry and linked them with the National Mortality Registry to estimate the survival functions for major occupational cancers: lung, pleural mesothelioma, urinary bladder and leukaemia. Assuming a constant excess hazard for each type of cancer, the authors extrapolated lifetime survival functions by the Monte Carlo method.
Objectives: This study aims to estimate the life expectancies and loss-of-life expectancies of workers with permanent occupational disabilities of the upper and lower limbs in Taiwan.
Methods: We collected all cases of permanent occupational disability in the upper and lower limbs from the Bureau of Labor Insurance database of compensation claims between 1986-2006; these data were linked with the national mortality registry to obtain a survival function. Workers were divided into eight groups according to their injury types, three of which fulfilled the condition of constant excess hazard and the survival functions were extrapolated to 50 years using a semi-parametric method.
Objective: To estimate the life expectancy (LE), quality-adjusted life expectancy (QALE), and their losses, in patients with pneumoconiosis in Mongolia.
Methods And Materials: All patients (n = 432) diagnosed with occupational pneumoconiosis during 1986-2006 were recruited from the registry of the National Research Center of Occupational Diseases, which was linked to the National Mortality Registry of Mongolia to obtain the survival function. We simulated age and gender matched referents group based on the life table in 2000.
Purpose: We explored covariates of the quality of life (QOL) in non-small-cell lung cancer (NSCLC) patients and made a comparison with healthy controls.
Methods: We assessed the QOL of 220 consecutive NSCLC patients at a university hospital. The QOL data were measured by the brief version of the World Health Organization's Quality of Life and by utility using the standard gamble method.
